Erm, I dunno much about NeXT, but FreeBSD (and other Unixes) can
run quite happily with the SLIP i/f address set to the ethernet card
address, since routing is done by the SLIP's destination address,
not by it's local address (AFAIK). I can say this (with a bit of
uncertainty) as the machine I am sending this from has a SLIP i/f to
Netcom (designation 'sl0'), and a Ethernet i/f toa 10bT LAN (designated
'ed1'). Both have been ifconfiged to have the same local IP address, and a
default route has been set to the gateway machine at the other end of the SLIP
link, with the ifconfig for the ed1 card setting the route
to the LAn correctly. Unless NeXT does things differently, only
one IP address should be needed by the NeXT. Certainly,
2 (or more) IP addresses are needed for machines with multiple IP i/f's
of a more traditional nature (ethernet, FDDI, etc), but I think most SLIP
implimentations would fall over if the 'en0' and the 'sl0' were given
separate IP addresses.

*However* I could be wrong, but this setup works fine for us.

Again, AFAIK, routed isn't needed unless there are multiple possible
routes to the smae destination. All that is needed for SLIP is a default
route entry, made just after the SLIP interface is brought up.

Hope this help, and doesn't confuse anyone!

BTW: Can anyone give more details of the Nutshell routing book,
     e.g. ISBN, etc? Thanks
